The Jewish Theological Seminary Library Launches “Jewish Books, Jewish Worlds,” An Interactive Exploration of Jewish Culture and Resilience Across Time

New digital experience invites a curated exploration of a thousand years of Jewish life through manuscripts, stories, and art

New York, N.Y., April 16, 2026 — Today, The Library of the Jewish Theological Seminary (JTS) launched “Jewish Books, Jewish Worlds,” a new digital museum experience, using its vast, rare collection of Hebrew books and manuscripts to showcase Jewish culture, imagination, and resilience to a global audience. Visitors can chart their own interactive path through Jewish history, following their interests and letting each discovery unfold into the next.

From manuscripts to ketubbot (traditional Jewish marriage contracts), ornately illustrated prayer books to historic correspondence between great Jewish thinkers, The JTS Library houses hundreds of thousands of works, many of which are now, for the first time, brought to life online — accessible to everyone, everywhere. 

“Worldwide, we’re seeing people investigate their Jewish identity,” said Dr. David C. Kraemer, JTS’s Joseph J. and Dora Abbell Librarian. “Our mission with ‘Jewish Books, Jewish Worlds’ is to facilitate discovery of the many elements of Jewish life, art, society, and culture found in JTS’s materials. We’re inspiring the Jewish future by sparking that discovery of our past.” 

“I am thrilled that the astounding treasures of JTS’s library will now be accessible, providing hours of engagement with the riches of the Jewish past and a taste of the breadth and depth of the Jewish experience,” said Chancellor Shuly Rubin Schwartz. “JTS is proud to have amassed and preserved the largest and oldest collection of Jewish historical materials in the world. What a privilege to now be able — through the marvel of technology and the outstanding leadership and efforts — of our visionary librarian, Dr. Kraemer; and our devoted Advisory Board Chair Joseph Rubin — to make this extraordinary legacy available to audiences worldwide.” 

Unlike most library websites, this one guides and explains without requiring scholarly training or prior knowledge. Visitors can start from a point of interest –– the Sabbath, or Jewish dress, or Persia — and then take a deeper dive through exploration-driven navigation.

Amid the featured works from the diverse and interconnected diaspora are:

• An illustrated 19th century manuscript that blends Judeo-Persian storytelling to tell the tale of Yusuf and Zulaykha –– a Sufi love story within a Jewish biblical tale. In the many materials created by Jews in Muslim lands, visitors can gain new insight into Muslim – Jewish relations by exploring centuries of Jewish-Muslim cultural exchange, coexistence, and shared heritage.

• The Rothschild Mahzor, a Florentine tome from 1490, where Jewish prayer meets Renaissance art. Commissioned by a famous Jewish family, its lavish illustrations exemplify cross-cultural creativity and Jews’ role in European art history.
  
• A letter from Maimonides, urging fundraising to ransom Jews captured by Crusaders. Bearing the philosopher’s own signature, the letter stands as a powerful example of continuity in Jewish values and communal responsibility as, even 800 years ago, a rabbi pleaded for hostages to be released.

Through these, and countless other works, visitors can wander through centuries of Jewish living and creativity. Inspired by the resilience of Jewish communities in the face of adversity and Jewish creativity in times of “Jewish Books, Jewish Worlds” showcases treasures from The JTS Library’s special collections. As a living website, the collection will continue to grow and evolve, inviting return visits and new discoveries over time.

“Across continents and centuries, Jewish communities have flourished –– often against all odds,” said Joseph Rubin, JTS Library Advisory Board Chair. “They celebrated holidays, marked life cycles, debated ideas, created art, and preserved memories. Now, ‘Jewish Books, Jewish Worlds’ offers a chance to wander through the manuscripts and artistic works they left behind. This is not only a testament to survival, but to the enduring joy and vitality of Jewish life.”

The collection offers diverse entry points for discovery, whether it’s encountering unexpected voices, immersing oneself in Jewish life across the world, or finding one’s place in the story as it continues in the present.
